Q. No.Osmotic pressure is the
(1) Pressure required to stop the water diffusing in
(2) Function of solute concentration
(3) More the solute, more is the pressure needed to stop endosmosis
(4) All of these
The net direction and rate of osmosis depends upon
1. Pressure gradient
2. Concentration gradient
3. Chemical potential
4. All of these
Apply concept of water potential and osmosis
The pressure applied in this experiment is
(1) Hydrostatic Pressure
(2) Colloidal pressure
(3) Osmotic pressure
(4) Pressure potential
Osmosis is a type of
(1) imbibition of solution
(2) diffusion of solvent
(3) evaporation of water
(4) diffusion of solute
The smallest amount of pressure needed to stop fluid from moving by osmosis is referred to as the
1. Turgor pressure
2. Water potential
3. Pressure potential
4. Osmotic pressure
Apply concept of water potential and osmosis
Solution of which chamber has a lower solute potential?
(1) Chamber A
(2) Chamber B
(3) Both will have equal values
(4) Cannot be predicted
In plant cell
1. Solute potential is contributed by cytoplasm
2. Solute potential is contributed by cytoplasm and as well as vacuolar sap
3. Solute potential is because of vacuolar sap only
4. Solute potential is caused by nucleoplasm
When water moves through a semipermeable membrane then which of the following pressure develops:
1. O.P.
2. S.P.
3. T.P.
4. W.P.
Which of the following statements does not apply to reverse osmosis?
| 1. | It is used for water purification |
| 2. | In this technique, pressure greater than osmotic pressure is applied to the system |
| 3. | It is a passive process |
| 4. | it is an active process |
Based on the figure given below, which of the following statements is not correct?
| 1. | Movement of solvent molecules will take place from chamber A to B. |
| 2. | Movement of solute will take place from A to B. |
| 3. | Presence of a semipermeable membrane is a pre-requisite for this process to occur. |
| 4. | The direction and rate of osmosis depend on both the pressure gradient and concentration gradient. |
